- Fri Mar 25, 2011 4:19 am #246105 Well, I still have my problem I checked timing its right on the money 16.5 degrees, replaced the dizzy and still no bueno. the only difference is my cranking is a lot smoother with rarely any misfires.

I ruled out the timing and dizzy, wth could it be? Could it be some loose wires at the plugs?

- Sun Mar 27, 2011 6:10 pm #246555 Update on my prob, well I just check continuity from the dizzy to the shock towers then to the ecu, got continuity from between each plug.I also sanded my ground on the thermostat housing(I think this helped get my car started) I got my car to start again with shortly after a cel 4, so I ruled out everything. imma see if cleaning out the plugs will solve the problem, clean out the corrosion.

*unLike many forum when u research they often leave u hanging onhow the problem was fixed, I will keep updating until the problem is fixed.

- Sun Mar 27, 2011 11:46 pm #246599 So now you're back to where you started with the CEL 4, except you've replaced the distributor? Or is it still the same one you started with? Also it should be held on by 3 bolts, not 2... does it look like someone elongated the holes to try to get it to fit?
What motor do you have?

- Mon Mar 28, 2011 2:05 am #246620 yes i replaced it with a brand new distributor and got cel 4 still. yeaa.. my new dizzy is held by 2 bolts just like my old one. i was pushing hard on my car with the old dizzy with two bolts, but i dont think it would cause cel 4.

with the new dizzy, it does start up much much better, and then the code comes on. im happy to get my car started at least for now.

i have the jdm b16a, and my dizzy is obd2?? its a TD-44u from the 2000 civic si my old one was TD-81u no signs of force fitment. i believe my old dizzy still works if i still have my CEL 4

and i just cleaned out each plugs, i even took out the wires from the plugs(cranksensor wires) and added dielectric grease on each pin, and also bent the pins bad in better shape to make sure of best connection. i tested continuity from the dizzy plug( not dizzy side plug the other side) to the ecu pin(b15 and b16), comfirmed i have continuity, so now that sounds like i got my connection hooked up, but when i plug everything back in, start up the car, and same thing again...

the last couple of things i can think of is my ECU went bad, or i was thinking last resort just wire the crank sensor wires directly to the ecu.

im runnin out of options


cliffs;
new dizzy same cel 4
starts up no problem
comfirmed continuity from dizzy plug to ecu

- Wed Mar 30, 2011 4:18 am #247071 so i wired the crank sensor wires(blue/green, blue/yellow) directly to the ecu(b15,b16) checked resistants between them, 380-385 ohms.......started her up. still code 4

The ECU must be bad then!!

but then on another note, i havent fixed my timing, but it runs, could a bad timing cause cel 4?

EDIT: i checked for a short to body ground this morning from the b15 pin. i have continuity when probing b15 pin and probing a ground. i checked for continuity on b13 and b11 pins, the other dizzy sensor, and i had no continuity, those are of course good since no cel for those. i kno where my short is i think, somewhere between the dizzy plug and the shock tower plug. maybe i damaged something when doing my axles and changing trans fluid. so close to solving this. but if i fix the ground issue and still have cel 4, its the ecu for sure.

- Thu Mar 31, 2011 1:39 am #247219 Not sure if you have done this... but take your dist out and set your Timing belt to TDC (top dead center). Make sure your marks are all lined up.

After you completed this, put in your dist in as this will make sure you are all set and lined up.

I had this problem, and i was about 10 degree off.

Good luck and let us know your situation.

- Fri Apr 01, 2011 3:50 am #247533 alright heres a good and bad update. CKP sensor, SOLVED. it was a short to ground body, whats funny is i just rechecked b15 to ground and this time i didnt get continuity( i will permantly fix later) so i thought i just test drive it. no codes no nothing good to go. but when i reverse out my driveway and put it in first gear it would backfire like crazy and stall violently. it back fires and mis fires so often i was scared to stall somewhere off my neighborhood and i tried to drive back home. i stalled on my driveway, i hate slanted driveways , took me a couple tries driving up my drive way without stalling, failed misserably. so next i tried backing up in my driveway. worked. the backfires as i was reversing was so severe, my cat converter fell off(mines bolted on). yea yea i kno i should do my timing. and STUPID me forgot to mark the dizzy when replacing it.

so i have a question, does having a too retarded timing cause alot of backfiring and misfires and stalls at low rpms in gear? or having it too advanced causes that??

at least im happy to get my one month old problem solved

- Fri Apr 01, 2011 1:09 pm #247600 Timing being too retarded will almost cause the car to stall. too advanced wil cause pre-detonation.
Rather than just rotation the distributor until it runs smoother, I recommend you properly check the timing with a timing gun since you're so close to solving this issue.

- Fri Apr 01, 2011 2:40 pm #247608 Yep that's gonna be next on my to do list thanks everyone for the help.

- Fri Apr 01, 2011 11:51 pm #247666 yup what Teal said. I had that happen and the car sat on the driveway for a week. Tweeking it everyday until i smack my head and said... stupid!!! check the timing and line it up right!!!

- Sun Apr 03, 2011 2:04 am #247925 yea i dont have a timing light to do the procedure, i cant afford one is there some kind of ghetto way to adjust timing, or just move the distributor back and forth til i hit the sweet spot??

i have a strobe light app on my phone(LED light) that can adjust the frequency and duration of the flash. i wonder if i can match the idle speed with the strobe light will be effective to at least see the timing marks while engine is at idle. might have to give it a try.

- Sun Apr 03, 2011 6:12 pm #248035 you can go to autozone or any auto place locally and rent it. this should help you get going.

thanks will do. just checked the mechanical timing, everythings spot on my ignition timings the only thing left to fix.
